Method and apparatus for providing emergency codes to a mobile device

Abstract

A method at a user equipment for obtaining emergency codes using a non-Third Generation Partnership Project (3GPP) network, the method including sending a request message to a network node, the request message containing an indication; and receiving, at the user equipment, a response message, the response message including at least one mobile country code (MCC), and the response message indicating an emergency number, type or category information, wherein the emergency number, type or category information is associated with the at least one MCC, and wherein the at least one MCC indicates a portion of a Public Land Mobile Network (PLMN) code to which the emergency number, type or category information applies.

The invention claimed is: 
     
       1. A method at a network node for providing emergency codes using a non-Third Generation Partnership Project (3GPP) network, the method comprising:
 receiving a request message from a user equipment, the request message containing an integer identifier corresponding to an information report; and 
 transmitting, to the user equipment, a response message, the response message including the information report, the information report comprising an indicator of an empty list of emergency numbers, the indicator including a mobile country code (MCC); 
 wherein the response message with the indicator causes the UE to overwrite a previously received list of local emergency numbers with the empty list. 
 
     
     
       2. The method of  claim 1 , wherein the indicator is a Uniform Resource Name (URN). 
     
     
       3. The method of  claim 2 , wherein the URN has a form of “urn:3gpp:sos-anqp:mccXXX”, where “XXX” represents the three digits of the MCC. 
     
     
       4. The method of  claim 1 , wherein the request message is received as part of an ANQP procedure, or an Internet Key Exchange Version 2 (IKEv2) procedure; and wherein the response message is transmitted as part of an ANQP procedure, or an IKEv2 procedure. 
     
     
       5. A network node configured to provide emergency codes, the network node comprising:
 a processor; and 
 a communications subsystem, 
 
       wherein the network node is configured to:
 receive a request message from a user equipment, the request message containing an integer identifier corresponding to an information report; and 
 transmit a response message to the user equipment, the response message including the information report, the information report comprising an indicator of an empty list of emergency numbers, the indicator including a mobile country code (MCC); 
 wherein the response message with the indicator causes the UE to overwrite a previously received list of local emergency numbers with the empty list. 
 
     
     
       6. The network node of  claim 5 , wherein the indicator is a Uniform Resource Name (URN). 
     
     
       7. The network node of  claim 6 , wherein the URN has a form of “urn:3gpp:sos-anqp:mccXXX”, where “XXX” represents the three digits of the MCC. 
     
     
       8. The network node of  claim 5 , wherein the request message is received as part of an ANQP procedure, or an Internet Key Exchange Version 2 (IKEv2) procedure; and wherein the response message is transmitted as part of an ANQP procedure, or an IKEv2 procedure. 
     
     
       9. A non-transitory computer readable medium for storing instruction code for providing emergency codes, where the instruction code, when executed by a processor of a network node causes the network node to:
 receive a request message from a user equipment, the request message containing an integer identifier corresponding to an information report; and 
 transmit a response message, the response message including the information report, the information report comprising an indicator of an empty list of emergency numbers, the indicator including a mobile country code (MCC); 
 wherein the response message with the indicator causes the UE to overwrite a previously received list of local emergency numbers with the empty list. 
 
     
     
       10. The non-transitory computer readable medium of  claim 9 , wherein the indicator is a Uniform Resource Name (URN). 
     
     
       11. The non-transitory computer readable medium of  claim 10 , wherein the URN has a form of “urn:3gpp:sos-anqp:mccXXX”, where “XXX” represents the three digits of the MCC. 
     
     
       12. The non-transitory computer readable medium of  claim 9 , wherein the request message is received as part of an ANQP procedure, or an Internet Key Exchange Version 2 (IKEv2) procedure; and wherein the response message is transmitted as part of an ANQP procedure, or an IKEv2 procedure.
